4 Claims. (Cl. 270-32) This invention relates to improvements in manifolding assemblies and more particularly to improvements in manifolding assemblies of the fanfold type, wherein a sheet of paper or similar material is folded along longitudinal lines to form long continuous superposed record strips with which one or more transfer strips are interleaved in transfer relation.

It is a general object of the invention to pro vide a manifolding assembly of the class mentioned, wherein an improved arrangement is provided whereby the assembly strips including the transfer strips can be separated from each other when in a typewriter or similar inscribing machine so that erasures and corrections can be.

quickly and easily made.

A further object is to provide an improved method of manufacture for manifolding assemblies of the class mentioned that can be economically practised either manually Or by automatic machinery.

A further object is to provide in a manifolding assembly of the class mentioned an improved arrangement and construction of the interleaved record and transfer strips whereby a set of form lengths or form sheets after inscription thereof can be quickly and easily severed from the complete assembly and the record and carbon sheets stripped or separated from interleaved relation with each other.

Other objects of the invention will be in part pointed out in the following detailed disclosure of an illustrative but preferred embodiment of the invention, and will be in part obvious as the disclosure proceeds.

The invention accordingly comprises an article of manufacture having the features, properties and relation of elements, and also comprises the several steps and the relation of one or more of such steps to each of the others, which will be exemplified in the article and method herein-' after disclosed, and the scope of the application of which will be indicated in the claims.

For a more comprehensive disclosure of the nature, objects and advantages of the invention,

closure of the illustrative embodiment and to the accompanying drawing, in which:

Fig. 1 is a perspective view of a manifolding assembly of the fanfold type embodying the inreference is had to the following detailed dis- Fig. 3 is an enlarged partially diagrammatic manifolding assembly; and

Figs. 4, 5 and 6 are fragmentary partially diagrammatic views illustrating the method of making the improved manifolding assembly.

Referring to the drawing for a detailed description of the illustrative embodiment there shown, a manifolding assembly I of the fanfold type has a plurality of relatively superposed long continuous record strips with long continuous carbon or transfer strips interleaved therewith in transfer relation. The strips are shown abnormally separated in diagrammatic fashion in order to disclose the arrangement more clearly. In the assembly shown there are three such record strips, an original record strip 2, a duplicate 3, and a triplicate l, carbon and transfer strips 5 being interleaved in transfer relation so as to transfer to the duplicate and triplicate record strips inscriptions made upon the original record strip. It will be understood that the assembly may have two or three or more record strips with the appropriate number of transfer strips. Each of the record strips is preferably provided with blank forms 6 arranged in a longitudinal series thereon, and the blank forms of the superposed strips are insuperp'osed relation with each other in the assembly, thus forming sets of superposed leaves or form sheets. Thus each record strip has a series of form lengths or form sheets, each having one of the blank forms 6, and the record strips are provided with longitudinally spaced transverse weakened severance lines 1 positioned between the adjacent form sheets and providing for severance of the form sheets along these lines from the complete assembly. The transfer strips 5 may also be provided with similar transverse weakened severance lines 8. severance lines may be made in any well known manner as by perforating, scoring, slitting and the like. The assembly i may be reversely folded along transverse fold lines preferably coinciding with the weakened severance lines I and 8, thus forming a zigzag folded supply pack 9 having a large number of sets of record and transfer leaves.

As mentioned, the manifolding assembly is preferably of the fanfold type, the superposed record strips 2, 3 and l'being formed of a single integral sheet of paper It or like material folded along longitudinal lines It. A longitudinal weakened severance line H extends along one marginal portion of each of the record strips, being continued throughout the length of each strip,

These weakenedcorrections.

'gitudinal severance lines thus forming longitudinal marginal binding margins or stubs I2. Each transfer strip is bound or attached to one of these stubs I2 by any well known binding means such, for example, as the adhesive attachments I3 shown diagrammatically in Figs. 2 and 3. At the opposite longitudinal margin of the assembly from the binding attachments I3, the longitudinal edge portions of the transfer strips 5 are inset from the adjacent longitudinal edges of the record strips, thus providing marginal selective grips whereby the record sheets can be gripped to the exclusion of the transfer sheets to facilitate separation of the transfer sheets from the record sheets of an inscribed set of sheets. The transfer sheets can be quickly and easily stripped or separated from the record sheets by gripping the marginal portions I2 and simultaneously gripping the opposite selective grips and exerting a quick jerk or pull whereupon the record sheets are torn from the binding along the weakened severance lines II while the transfer sheets remain attached to the binding, thus causing the record and transfer sheets to be separated.

In manifolding assemblies of this type it often becomes desirable to make erasures and corrections on the underlying record sheets when the assembly is in writing position in a typewriting or similar inscribing machine. I-Ieretofore, it has beendiificult to make such erasures with the assembly in the machine and it has been found necessary to remove the assembly from the machine for the purpose of making the erasures and However, in this improved assembly such erasures and corrections can be easily made while the assembly is still in position in the writing machine.

In order to accomplish this advantageous result the transfer strips 5 are formed with elongated lines of separation or slits, such as indicated at M in Fig. 3. These elongated slits I4 preferably extend entirely through the transfer strips. As shown, the elongated slits it are substantially in depthwise alignment in the assembly with the longitudinal weakened severance lines I I of the record strips, and, as shown, they are preferably positioned at each of the end sections of each transfer shee't" of each sheet set.

These slits I i are positioned at longitudinally spaced intervals throughout the length of each transfer strip 5 and, as shown, they are preferably positioned with their ends adjacent to the transverse weakened severance lines 8, but short 'integral sections or ties I4 are preferably provided at one or both sides of each severance line 8.' These slits I4 may extend inwardly in each transfer sheet to any desired extent but their adjacent ends do not meet, thus leaving a considerable integral length of each transfer sheet of its original strength so that the transfer sheets remain attached to the binding by the adhesive attachments I3. Although the elongated slits I4 are shown as being positioned at each of the opposite ends of each transverse sheet, they may in some cases be omitted from the bottoms or rear ends of the sheets.

When the manifolding assembly is inserted over the platen of a typewriting machine and it is desired to make erasures on the underlying record sheets of the assembly, this can be easily done by separating the forward ends of the assembly sheets.

Thus the original record sheet or strip 2 can be separated from theunderlying sheets by severing the forward parts of the lon- II, and the underlying integral sections or ties I5 are preferably provided at one or both sides of each severance line I. The ties I I and I5 hold the edges of the paper in place after severance along the lines I and 8, but are easily severed when desired. The slits I5 may be omitted but it is convenient to construct the assembly with both the slits I4 and I5 because these slits can be simultaneously made after the record and transfer strips have been assembled in their normal operative position. Also, the slits I5 provide for easier separation of the record sheets from the binding I2 during the sheet stripping operation because of the shortened attachments of the weakened lines I I. This is a decided advantage where there are a large number of sheets in each set or where the sheets are exceptionally long.

In the preferred method of making the improved assembl a, long continuous record sheet It is provided as indicated diagrammatically in Fig. 4, the blank forms 6 being printed thereon at opposite sides of the sheet so as to be superposed in transfer relation when this sheet is fanfolded. The longitudinal weakened severance lines I I are formed in this sheet by an appropriate scoring or perforating tool or implement and the weakened fold lines III are similarly formed, but the fold lines II] are scored or cut to a greater extent than are the lines II so as to weaken the sheet to folding resistance along the lines ID to a greater extent than along the lines II. It will be noted that it is undesirable to have the strips fold along the weakened lines II. This greater weakening of the lines III to folding resistance may be accomplished by cutting the paper to a greater extent than the cutting at the lines II, or by scoring or cutting the paper part way through the thickness thereof. Thus the resistance to folding along the lines Ii] can be made as soft as desired. The transverse weakened severance lines I may be formed either before or after the sheet IE5 is folded and either before or after the carbon strips 5 have been interleaved with the record strips.

When the sheet It has been longitudinally scored or weakened along the lines It and II, as described, the forward end portion of the sheet is initially folded along the lines III to bring the record strip end portions in superposed relation, as suggested by the partially folded condition of the strips as shown in Fig. 5. The forward folded end of the sheet is then led over a guide, such as indicated "at IT, and the sheet in this condition is then pulled or fed forwardly over the guide. Any appropriate feeding mechanism may be used for this purpose or it may be done by hand. This action causes the sheet to fold progressively along the weakened fold lines III throughout thelen'gth of the sheet becauseof the folding effort or tendency exerted. Due to the differential Weakening of the lines III and II, this folding is always confined to the lines I0 because the resistance to the folding along these lines is much weaker than along the lines II.

The carbon strips may be interleaved in transfer relation with the record strips either during the folding operation of the sheet Hi, just described, or at some other time. When the carbon strips 5 are interleaved in the assembly, the adhesive is applied and the attachment of these strips to the binding margins I2 is completed.

When the record and carbon strips are all assembled together in the assembly, the elongat ed slits M and [5 of the carbon and record strips are then made at the same time by means of an appropriate cutting tool or implement, these slits being made to extend entirely through the assembly including both the record and carbon strips and coinciding with the weakened lines I I. The assembly may be fed or advanced by any appropriate feeding mechanism for this purpose. When this operation is completed the assembly is ready for use and can be zigzag folded into the supply pack 9, as described.

Since certain changes may be made in carrying out the above method and in the construction of the assembly without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
